[FIXED] Process Codes in the Middle of a SequentialTransition- JavaFX

Issue

I am trying to execute a SequentialTransition, but between the animations, I need to execute some commands.

My problem is that it is always executing the last commands passed on the node. Is there any way to fix this?

Where is "is ignored" is the code that I need to be executed in the first animation, then where this "is executed" is the code that I need to be executed in the second animation.

Thanks

private void startAnimation(){

    vb_adv.setPrefWidth(197);
    ap_services.toBack();// Is ignored
    vb_adv.toFront();// Is ignored
    ScaleTransition expandAdvertising = new ScaleTransition(Duration.millis(2000), vb_adv);
    expandAdvertising.setToX(2);
    expandAdvertising.setCycleCount(2);
    expandAdvertising.setAutoReverse(true);

    ap_services.setPrefWidth(124);
    ap_services.toFront();//is executed
    ScaleTransition expandService = new ScaleTransition(Duration.millis(2000), ap_services);
    expandService.setDelay(Duration.seconds(3));
    expandService.setToX(3.7);
    expandService.setCycleCount(2);
    expandService.setAutoReverse(true);

    SequentialTransition sequence = new SequentialTransition(expandAdvertising, expandService);

    sequence.play();
}

Solution

In the code as you currently have it, you move ap_services to the back of the z-order, and vb_adv to the front:

ap_services.toBack();
vb_adv.toFront();

Then you create and set up you ScaleTransition. Note that doing this part takes essentially no time; all you are doing is configuring the animation which will run later.

The next thing you do is to move ap_services to the front:

ap_services.toFront();

Note that this will happen essentially immediately after the previous calls to toFront() and toBack(), and of course this negates the effect of those calls. So your initial calls are actually executed (not "ignored"), but you immediately do something which undoes their effect.

What you really want is to execute ap_services.toFront() after the ScaleTransition finishes. You can do this by putting that call in an onFinished() handler:

// ap_services.toFront();
expandAdvertising.setOnFinished(e -> ap_services.toFront());
